Characterization and formulation of therapeutic macromolecules using light scattering
March 24, 2021
11 am to 12 pm EST

Webinar Description:

Given the complexity of biological macromolecules used for therapeutic purposes, detailed characterization is both essential and challenging. Some of the most important tools for analyzing the properties and behavior of biologics are based on multi-angle light scattering and dynamic light scattering, which directly determine molar mass, size, stability and interactions. This webinar will provide a brief introduction to these techniques, then several case studies will be presented that utilized dynamic light scattering (DLS), multi-angle light scattering with size-exclusion chromatography (SEC-MALS), and composition-gradient multi-angle light scattering (CG-MALS) as analytical tools for the characterization and formulation of macromolecules ranging from virus-like particle-based vaccines to monoclonal antibodies.

Key Learning Objectives:

  • The technology and capabilities of DLS, SEC-MALS and CG-MALS
  • How DLS is applied to study the aggregation and, stability of biologics
  • The importance of SEC-MALS for determining absolute molar mass and size of proteins, complexes and self-assemblies
  • How composition-gradient light scattering characterizes macromolecular interactions to better understand formulation stability and propensity to aggregate
